How many PSI is a mason jar rated for

I was thinking about doing this with a water filter canister (cost 40.00 plus fittings) but I'm cheap and out in the garage I have a mason jar and some copper pipe, fittings and a stainless screen just waiting to become a randell (cost zero) but my concern would be popping the lid or worse if it required a little PSI push to get the beer through the hops. what has been your experience using it.
